Detachable miter connector

Description:

Frames made of square tubes are required for numerous purposes, e.g. for shelves, racks, gondolas, etc. ". They are used in the Manufactured in such a way that they are mitred like wooden frames and the mitered surfaces are joined together, e.g. by welding. You can also releasably connect them by cutting off the corners with short leg parts, for example Welded pipe section with a smaller diameter, which is pushed into the frame tube as a plug-in connection.

The innovation is that the frame parts are neither welded nor pushed into one another, but rather by means of a solid connecting piece be jammed with an eccentric housed therein.

With the previously usual welding, the weld seam had to be ground off as a result of which the frame was structurally considerably weakened, since frames of this type are often only 0.4 mm thick Sheets are produced. The appearance of the frames also suffered in the areas that were revised in this way. Plug connections too are not satisfactory because they are not stiff and reliable enough. They also require 3 joints instead of a single one at each frame corner.

The solution described here provides that the frame tubes are mitred as before, but taut in a new way and yet can be detachably connected to one another. For this purpose, a miter connector is inserted into the inside of the tube at the frame corners introduced. It consists of the miter bracket and the eccentric screw. These parts can be made of iron, metals or plastics exist.

Details will be explained using examples.

The miter connection according to ATdId. 1 and 2 "consisting of the G _e nrungs ~ angle (1) and the eccentric (2). The bevel (l) is introduced ^ in Rohrstüek (3) and fixed by pressure in a bead (4). Me fixing may vary Depending on the type of use, this can also be done using clamping sleeves (5) from ATdTd. 2, pins, screws or the like.

The miter angle (l) in ATdTd. 3 shows the dimensions of the clear ! ohrmize with appropriate clearance and can be given recess grooves or the like on the contact surfaces in order to save weight etc. to achieve. One of the angled legs is on the inside a bead (4) or hole (5) is provided to fix a pipe section (3). The miter angle can vary depending on the use get these recesses inside or outside as well as on both sides. There are two opposing recesses on the other angle leg (6), which are connected by a long or oval hole (7), incorporated. The miter angle also has an incision (8) in order to be able to record any miter differences and burr formations «

Fig »4 illustrates an eccentric screw (2) with the nose

(9) and the eccentric head (10) with hexagon socket or square (11

The uses of the miter connector are shown in Figures 1 and 2. After setting the miter angle (l) in the pipe section (3) the pipe section 12 is pushed on and the eccentric screw (2) through the bore (13) in the pipe section (12) into the Opening (7) of the miter bracket inserted. The pipe connection has a distance dimension X which is smaller than the eccentric dimension the screw (2). By turning this screw, the pipe section (12) is due to the eccentric design of the screw head

(10) to the shaft, which flies against the wall of the opening (7), pressed against the pipe section (2) and the miter is thus closed. The rabbit (9) of the screw is pushed onto the surface (14) by turning and thus prevents it from falling out.

Figure 5 illustrates a perspective view of a miter joint in a closed, assembled version and shows the pipe bore (13) with the screw head and the bead (4), which * The eccentric screw lie on the inside of a frame screw can be handled with a pin or socket wrench.

The special advantages of this price increase are summarized as follows: - 3 "

Association by port case of labor for that otherwise "previously usual welding and grinding or polishing work,

Quality improvement because the material is close to the G honor unchanged in its original condition and strength remain,

Can be used for assembly by the recipient without the requirement of specialist knowledge,

Reduction of packaging and storage costs, elimination of bulkiness in the i ⁿ abrication process, shipping and recipient area,

Equivalent strength and rigidity as with welds in contrast to the unsatisfactory strength and rigidity of plug connections,

Higher utility value of the frames through easy dismantling as often as required and easy to adjust.
